I am thinking about going to Art Institute online program, however they are based on quarter system so credit requirement for BA is 180 credits. 180 credits translates into 55 classes and at $1381 per course the total is $82,360 cost for BA. Is this generally how quarter based schools work? Is AI cost of obtaining BA reasonable average cost for good school? I have seen other online programs with the average 120 credit requirement for BA, so are semester based schools more expensive per course so it averages about the same in the end, with just difference in schedule structure? Any insights from anyone would be truly appreciated.
